7555 C MAL/ANS Patented Apr. 12, 1949 UNITED STATES PATENT OFFICE 2 Claims.

The present invention relates to oil burner systems generally and, more particularly to an improved form of steam generator which is especially useful in burner systems.

In my United States Patent No. 2,012,676, I disclose and claim a burner system and burner, and the present invention is in, one aspect thereof, an improvement on the said system.

An object of the invention, therefore, is to improve oil burner systems.

Another object is to provide an improved steam generator which operates as a flash boiler.

A further object is to provide a steam generator in which sediment and foreign matter is kept out of the steam discharge line.

Other and more specific objects will become apparent as the following description proceeds in connection with the accompanying drawings in which:

Fig. 1 is a vertical sectional view of the generator and is taken on the line 2-2 of Fig. 2;

Fig. 2 is an elevation of the steam generator embodying the invention; and

Fig. 3 is a schematic showing, by way of example, of a steam generator of this invention included in an oil burner system.

Referring for the present to Figs. 1 and 2 of the drawings, l indicates the generator in its entirety and it is seen to comprise upper and lower generally hemispherical parts l4 and [6 which are joined in any suitable manner as by a weld ll, for example. The upper part [4 is provided with a water inlet l8 shown as a pipetapped hole suitable for receiving the pipe, for example, the pipe IQ of Fig. 3 of the drawing. It will be understood that the water or other conduit may be brazed or welded into position if desired.

The lower part 16 of the generator is provided with a clean out plug 2| seated in a threaded opening in a boss 22.

The upper part l4 of the generator is provided with a boss 24, apertured as shown at 26 to support a baffle device or member 28. The member 28 has a generally hemispherical wall 29 and is provided with a bottom wall 3|. Generally U- shaped baffle walls 33 and 36 pass upwardly around the water inlet l8 and a steam port 36, respectively.

. The member 28 is held in position by a neck 33 which seats in the aperture 26 and is upset or expanded as shown at 4| in the enlarged upper end of the aperture 26.

In operation of the steam generator Ill, a gas burner, or the like (not shown), supplies 2 heat thereto and water is admitted through the connection I8. This water or the resulting vapor and/or steam passes between the wall of the hemisphere l4 and the wall 29 within the confines of the baffle 33. When the fluid flowing as stated reaches the interior of the part IE, it is then substantially completely in the form of steam. Any sediment or foreign matter is deposited at the bottom of the part l6 and mainly on the top of or adjacent to the plug 2|.

The steam flows between the walls of the bafile 34 and the hemisphere l4 and through the port 36 to the interior of the member 28. A steam discharge pipe, for example the pipe 44 of Fig. 3, is connected to steam utilizing apparatus (not shown). When the quantity of water, under a given pressure, is increased, the steam pressure will be substantially unchanged, but the steam temperature will be lowered.

Fig. 3 shows, by way of example, a portion of the system described and claimed in the above noted patent and illustrates one use of the steam generator of this invention. Pipe 45 corresponds to pipe 2!) of the patent and connects to a suitable water supply source. Valve 48, which is preferably adjustable as to quantity of flow of pressure or both, is a pressure reducing valve and corresponds to the valve 28 of the patent. Valve 49 is the control valve and is operated by a lever, or the like, 5|. Valve 49 corresponds to the valve 24 of the patent. Stop valves, check valves or the like may be included if desired. Pipe l9 connects with the generator Ill and corresponds to the pipe 32 of the patent. The steam outlet pipe 44 corresponds to the pipe 48 of the patent and a portion thereof may effect operation of the valve 49 by the lever 5| as described in the patent. An auxiliary burner, as mentioned above, may be used to supply heat to the generator l0 before the main burner (not shown herein) is in full operation. Where the generator I0 is used as a boiler apart from an oil burner or the like, a burner using any kind of fuel may be employed to generate steam.

From the foregoing it is believed that the operation of the system of Fig. 3 will be apparent.

What is claimed is:

1. A steam generator which comprises a hollow spherical body having an outlet at its top and a. water inlet adjacent thereto, a hemispherical hollow member having a hollow neck disposed tightly in said outlet to suspend the member within the body in the upper part thereof with its walls spaced from the spherical body. said member having a steam inlet disposed therein on the lower side opposite the water inlet in the body, a guiding baflle plate disposed between the walls of the body and member to guide the fluid down from the water inlet into the interior of the body below the member, a guiding baflle plate disposed between the walls of the body and the member to guide the generated steam up therebetween from the interior of the body to the steam inlet of the member.

2. A steam generator which comprises a hollow spherical body having an outlet at its top and a water inlet adjacent thereto, a hemispherical hollow member having a hollow neck disposed tightly in said outlet to suspend the member within the body in the upper part thereof with its walls spaced from the spherical body, said member having a steam inlet disposed therein on the lower side opposite the water inlet in the body, a guiding baflle plate disposed between the walls of the body and member to guide the fluid down from the water inlet to the interior of the body below the member, a guiding balfie plate dis- REFERENCES CITED The following references are of record in the file of this patent:
